5 Claims, 9 Drawing Figures PATENTEDSEP 41m 3.75 .499 SHEEI 3 UP 3 v BOX WITH FIVE PANEL ENDS BACKGROUND OF THE INVENTION SUMMARY OF THE INVENTION It is an object of the invention to provide a box with five panel ends for added strength.

It is a further object to provide a box with five panel ends which can be formed of a one-piece blank of generally rectangular shape.

It is a further object to provide a blank which is simple and economical to manufacture, can easily be set up into a box with five panel ends, which is efficient and well suited for its intended purpose.

DESCRIPTION OF THE PREFERRED EMBODIMENT els 15, inner end panels 16, intermediate side partial panels 17, intermediate end panels 18, and intermediate end half panels 19. The outer bottom panel 11, the outer side panels 12, the inner side panels 13 and the inner bottom half panels 14 are interconnected along generally parallel score lines respectively 20, 21 and 22. The outer end panels 15 and the end half panels 19 are connected respectively to the bottom panel 11 and the outer side panels 12 along generally parallel score lines 23. Intermediate side panels 18 are connected to the intermediate end half panels 19 along score lines 24. The outer end panels 15 and the inner end panels 16 are connected along score lines 25. The intermediate side partial panels 17 are connected to the inner end panels I6 along score lines 25a.

The bottom panels 11 and 14 may be provided with ventilation holes 26 which are positioned to match when the blank is folded into a box and the inner bottom half panels 14 overlie the outer bottom panel 11.

The various end panels l5, l6, l8 and 19 may be provided with handholes 27 or half handholes 27a which are positioned to match when the blank is folded into a box and the said panels are superimposed, thus constituting a single handhole at each end of the setup box. The inner bottom half panels 14 may also be provided with a thumb hole 28 which will permit gripping the panels for knocking the box down, if necessary for shipment in flat form.

The corners of the various panels may be provided with circular cutouts 29 which will appear as cutouts in the bottom and top corners of the setup box. This permits insertion of a metal reinforcing member 30 (FIG. 2) in the upper rim of the box when the panels are folded in place. It also facilitates the folding and setting up of the box. Extending outwardly from the ends of the score line 23 are slots 31 which separate the panels 13 and 18. Likewise the slots 32 at the ends of the score lines 20 separate the panels 15 and 19.

FIGS. 3 through 6 illustrate how the blank can be set up into a box without the necessity of any stitching, tape or tools. The panels 12 hinged to the outer bottom panel 11 are erected to a generally upright position. The intermediate end panels 18 are folded to lie flat against the intermediate end half panels 19 with the panel 18 on one side being folded inwardly and the opposite panel 18 on the other side being folded outwardly (FIG. 3). The four panels 18 and 19 are then superimposed so that the end of one panel 18 butts the end of the other panel 18 at approximately the center of the end. Panels 15 are raised to an upright position bottom half panels 14 flush against the bottom panel I l 'with the long edges of the panels 14 butting against each other along the middle of the bottom (FIG. 6). It will be seen that the various handhole cutouts match to provide a handhole at each end of the box. FIGS. 7, 8 and 9 illustrate the positions of the various panels in the ,ends of the setup box.

When the metal reinforcing member 30 is to be included in the box to strengthen the rim of the box, such member isinserted before the inner panels are folded over the ends and sides.

Thus among others, the several aforenoted objects and advantages are most effectively attained. Although a somewhat preferred embodiment of the invention has been disclosed and described in detail herein, it should be understood that this invention is in no sense limited thereby and its scope is to be determined by that of the appended claims.

Having thus described the invention, what is claimed 1. A four sided box formed from a generally rectangular blank of sheet material cut, scored and folded into said box having a bottom, two opposite side walls and two opposite end walls; each end wall comprising an outer end panel hinged to the bottom, an inner end panel hinged to the top of the outer end panel, a first intermediate end partial panel hinged to a side edge of one of the side walls, a first intermediate full panel hinged to the top of the first intermediate end partial panel and folded outwardly to lie flat against the outer face of the said first partial panel, a second intermediate end partial panel hinged to the opposite side edge of the other of the side walls, and a second intermediate full panel hinged to the top of the second intermediate end partial panel and folded inwardly to lie flat against the inner face of the said second partial panel, the sum of the widths of the said partial panels not exceeding the width of the end wall, said intermediate panels being positioned between the inner and outer end panels, the said panels of each end wall being cut out to provide a handhole for carrying the box; each side wall comprising an outer side panel hinged to the bottom, an inner side panel hinged to the top of the said outer side panel, and side partial panels each hinged to the side edge of an inner end panel, the inner and outer side panels being superimposed with the side partial panels positioned therebetween; the bottom comprising inner bottom partial panels hinged to the bottom edges of the opposite inner side panels, the sum of the widths of the said inner bottom partial panels being approximately equal to the width of the bottom, whereby the said inner bottom partial panels will butt along their facing edges.
